7. The Economics of NbS: moving from evidence to decision making in policy, finance and infrastructure investments

Key barriers to effectively implementing, scaling up, and mainstreaming Nature-based Solutions (NbS) include a lack of knowledge of decision-makers of the true value of ecosystems, how these benefits are distributed, and/or their ability to be included in specific financial streams.  In this session, we will present some of the latest evidence on the extent to which NbS can deliver economic development through enhanced water security, food security, and climate adaptation, and provide expert insights into what works and what doesn’t for moving from economic evidence to action with public and private stakeholders. This session will begin with an overview of the key societal challenges that NbS economic valuation can address, and the key challenges and opportunities that economists face in motivating stakeholders to action for the decade ahead. Through three case studies from around the globe, we will then explore economic valuation and biophysical modeling approaches, equity and inclusivity considerations, and best practices and opportunities for scaling NbS interventions through partnerships, communications, financing, and policy solutions.
